LAMP 0R LANTERN.

SPECIFICATION forming part of Letters Patent No.1520,866, dated June 5,1894.

Application filed March 21, 1892. Serial No. 425,788. (No model.)

To all whom it may concern).-

Be it known that` I, LOUIS W. SCHEFERS, of the city of St. Louis, Stateof Missouri, have invented certain new .and useful Improvements in Lampsor Lanterns, of which the Yfollowing is a full, clear, and exactdescription, reference being Vhad to the accompanying drawings, forminga part hereof.

My invention relates to an improved lamp 0r lantern, and consists in thenovel construction, combination and arrangement of parts hereinafterdescribed and designated in the claims.

The object of my invention is to provide an improved detachable drip-cupfor the oil fount, by means of which said oil fount will be connected tothe frame of the lamp or lantern and held in a vertical position.

A further object of my invention is to provide improved wick-adjustingdevices which may be operated through the vertical central passage inthe detachable drip-cup to adjust the wick, without detaching thedrip-cup from the frame, and without separating the oil fount from thedrip-cup. .K

In the drawings: Figurel is a sectional elevation of a lantern embodyingmy invention. Fig. 2 is a side elevation of the oil fount and the burnerattached thereto. Fig. 3 is a transverse section taken on the line ofFig. 2. Fig. 4 is a bottom plan view of the oil fount and drip cup. Fig.5 is a horizontal cross-section, taken on the line 'y-y of Fig. 2, andFig. 6 is a top plan view of the drip cup detached.

Although my invention is applicable to various styles of lamps andlanterns, I have shown it herein applied only to a lantern.

l indicates a hand-lamp which is particularly adapted to be used byrailway-conductors and others, and which embodies myinvention.

2 represents the base of the lamp which is open at the bottom, andhaving an upper tubular-portion 3 to which the ordinary parts of thelamp are attached, such as chimney, &c.

To the interior cylindrical surface of the base tubular portionof thelampv is attached the upper edge of a pipe or tube 4, in which areformed screw threads, the same ,being pressed therein, around which thedrip cup is adapted to be screwed, as best shown in Fig. 1.

5 indicates the oil fount which is provided at its lower end with acylindrical reduced portion, and this reduced portion is surrounded by averticalscrew-threaded flange 6, the upper end of which is secured tosaid fount, and the lower end. of which is free, so that an annularspace is provided between said re- 6o duced portion and said flange, fora purpose hereinafter mentioned.

7 indicates the drip cup, whichk is constructed in the form of anannular trough having concentric outer and inner'vertical Walls, the 65upper edge of which is free, and the lower edge of which is attached tothe bottom 10 of said drip cup, so that the upper end of said drip cupis open, and its lower end closed. The drip cup is constructed of thinmetal and 7o is so shaped as to be easily attached to the fount 5 andthe lamp proper, and which is adapted to receive all the waste oilpassing from the outside of said fount. The inner and outer verticalconcentric walls of said drip cup ortrough are provided withscrew-threaded portions S and 9 respectively, which are adapted toengage the screw-threaded ange 6 and the pipe or tube 4, said outer wallof said drip cup being located upon the outer 8o surface of said pipe ortube, and the inner wall of said drip cup being located upon the innersurface of said flange in the space between it and the reduced portionof said oil fount. By this means the drip cup or annular 8 5 trough isdetachably secured to the frame of the lamp or lantern, and the oilfount is detachably secured toand supported by said drip cup, so thatwhen said drip cup is detached from said frame, said oil fount will be9o detached with it, and'afterward said drip cup may be separated fromsaid oil fount. The waste oil passing off from the fount 5 is re-`ceived by the space 11 formed by said screwthreaded portions 8 and 9, asclearly shown 95 in Fig. l of the drawings. After the trough has beenattached to the O il fount 5 as before stated, the screwthreadedextension of portion 9, of the said trough can easily be screwed uponthe screw-threaded pipe or tube roo 4, and thus the parts removablyattached and the trough placed in position to receive all the waste oilthat may pass from said oil fount.

Having given a description of the construction and the manner ofattaching the oil-fount 5 to the lamp-casing, I shall now proceed todescribe the construction of the burner and the means for operating thesame without removing or detaching any of the parts previously referredto.

In constructing the oil fount 5, I dispense with the screw-threadscommonly employed for attaching the burner to the same and in placethereof I employ fastening devices which will more eifectually lock thesame and further economize the time and labor generally employed inattaching and detaching the burner.

The upper portion or topot' the oil fount 5 is provided with an annularflange 12, surrounding the opening formed therein, which is adapted toreceive the lower and interior portion 13 of the burner I4, and by whichmeans the said burner is held in its proper position in said oil fount.The lower portion 13 of the said burner is provided with a horizontalprojecting flange 15, which is adapted to be received by the hooks 16attached to the top of the oil fount 5. Adjacent the annular iiange l2the ends of the hooks project in opposite directions, as best shown inFig. 2 of the drawings, preventing the burner from being removed fromthe oil fount when in a certain position. The annular horizontalprojecting flange is provided with cutaway portions 17, which areoppositely located, as best shown in Fig. 5 for allowing the hooks 16 tobe removed from their locked position when the burner is turned in sucha position that the said cut-away portions register with the said hooks.

In order to hold the burner 14 in a locked position, or for preventingthe same from turning, I employ a mechanism that I shall hereinafterdescribe.

In order to regulate the wick of the burner from the outside of thelamp, or in other words Without removing the oil fount 5 from thecasing, I employ a mechanism, which I shall now proceed to describe.

18 represents the shaft,which,when turned, operates the Wick in eitherdirection, to which is attached the ordinary spur wheel or wheelslocated within the burner and in contact with the wick, whereby the sameis raised or lowered when the shaft is turned in the proper direction.

To the projecting end of the shaft 18 is secured a spur wheel 19, whichis fixed thereto in any desirable manner, the teeth of which are adaptedto engage with a worm 20 carried by the upper end of the operating shaft2l.

22 represents a pipe or tube which extends through the oil fount 5 andprojects a suitable distance above the top of the same, which is inwater tight connection to said fount and through which the operatingshaft 2l is passed or located, and adapted to be turned therein.Encircliug the said shaft 21 and irnmediately above the upper edge ofthe pipe 22, is a collar 23, which holds the said shaft in its properposition and prevents the same from passing out of the said pipe ortube, the construction of which is better shown in Fig. 3. The worm 2Oattached to the upper end of the operating shaft 2l, may be constructedin any suitable manner, but for the sake of simplicity and cheapness Iemploy a length of Wire, and form the same in any desired shape, andsecure the said Wire to the shaft in said position, which answers thepurpose exactly.

To the lower end of the operating shaft 2l is attached a knob 24, whichprovides means for readily turning the said shaft, the said knob beinglocated below the bottom of the said oil fount.

To the side ofthe oil fount 5 and near the upper edge of the same isfixed a fiat spring 25, the upper end of which projects a suitabledistance and said end is provided with a circular depression or cut-awayportion 2G, which is formed in the same for receiving the projecting endof the shaft 18 for preventing the burner from being turned only whenthe said spring is moved from the said shaft, as best shown in Fig. 2 ofthe drawings.

When it is desired to regulate the wick of the burner, the operatingshaft 2l is turned without in any way removing the oil fount from thelamp, which in turn causes the spur wheel 19 to be turned or rotated andconsequently the shaft 18 has action upon the wick in the mannerpreviously described.

An important portion of my invention is the construction of thedetachable drip cup in the form of an annular trough, having a verticalcentral passage or opening surrounded by the vertical inner wallthereof, and through which passage the wick moving shaft projects belowthe bottom of the oil fount, the said vertical passage of said troughbeing of sufficient size to permit detachment thereof by the revolublemovement without interfering with said wick moving shaft.

It is desirable that the trough be detachable for the reason that it'may be readily separated from said fount and inverted without invertingthe fount.

The burner in lamps orlanterns of this class is not fitted oil-tight tothe oil fount, so that if said fount should be inverted for the purposeof throwing the drippings out of the trough, oil would flow out throughthe wick tube and through the vent opening in the burner, which is notto be desired.

From the foregoing description it will be seen that all the parts aredetachable and very easily cleaned, and further by the use of theannular trough and the construction of same, all Waste oil is receivedand prevented from passing out of the lamp as is very common in lamps ofthe ordinary construction.

I am aware that prior to my invention a revoluble wick-moving shaft hasbeen extended vertically through the oil-fount so as to be accessible atthe bottom of said fount, and so that the wick maybe adj usted withoutremoving the fount from the frame of the lamp or lantern. I am furtheraware that a vertical projecting drip-catching rim has been xed upon theupper outer side of the oilfount interior of the supporting frame. I amfurther aware that prior to my inventiony drip cups devoid of anyvertical central passage have been located upon the bottom of the oilfounts of lamps or lanterns, and I hereby disclaim such as of myinvention when used separately.

Having fully described my invention, what I claim isl. The combinationwith a handle, and a glass globe, of the frame, having a hollow baseprovided with an interior depending annular screw-threaded flange, of adrip cup in the form of an annular-trough having concentric verticalouter and inner walls, said outer wall being screw-threaded at its upperend so that its screw-threads will mesh with the threads of said flangeon the base, and an oil fount provided at its lower end with an annularthreaded liange adapted to mesh with the threaded inner vertical wall ofsaid drip cup, andthe drip cup being detachable from the frame, and theoil fount detachable from the drip cup, said oil fount being normallysupported in position solely by its connection with said drip cup,substantially as herein specified.

2. The improved lamp or lantern,constructed with a burner having'ahorizontal outwardlyprojecting flange provided with cutaway portions 17,and an oil-fount having an opening in its top, an annular upright flange12 encircling said openin g and adapted to be en-gagedby said burner,hooks 16 attached to the top of said oil fount so as to register withsaid cut-away portions 17 of the burner-Hange and be engaged bytheangeon the burner, portions of the heads of said hooks normallyprojecting above the flange on the burner, the horizontal burner shaft1S carried by said burner and having a projecting end, and an uprightspring 25 having a free upper end and its lower end fixed to said fountand provided with a depression 26 at a point adjacent to its free upperend, said depression being arranged to receive the projecting end of thesaid shaft, and thereby lock said burner in position against rotationupon said oil fount, substantially as and for the purpose set forth.

3. The improved lamp orlantern, constructed with a frame an oil fount, adrip cup having a vertical wall surrounding a passage or opening whichis formed in said drip cup, means by which the bottom of said oil fountis de.- tachably secured to 'said drip cup, and a wickmoving shaftextending through said passage or opening of the-said drip cup, andconnected at its upper end with the burner shaft, whereby the wick ofthe burner may be adjusted without removing the oil fount from the frameof the lamp or lantern, and the drip cup may be separated from the frameof the lamp or lantern, and from said oil fount, to remove waste oilfrom said cup, substantially as herein specified. v

4E. The improved lamp or lantern, having a frame an oil fount, a dripcup in the form of an annular trough, to which the bottom of said oilfount is separably attached to support said fount, said drip cup havinga vertical passage or opening interior of its vertical side wall andsurrounded by said wall, means for connecting said drip cup to said oilfount and separating the same therefrom by a revoluble movement, and avertical wick moving shaft'which extends through said vertical passageof said drip cup, and through the body of said oil fount, and has itslower end accessible'in said passage of said drip cup at the lower endof said oil fount, substantially as herein specified.

5. The improvedlamp orlantern,constructed with a frame having a base orstand, a vertical pipe or tube 4f providedwith screw-threads andconnected at its upper end to said base or stand, so that its lower endwill be free, an oil fount 5 provided at its lower end with acylindrical reduced-portion, a vertical screwthreaded flange 6 havingits upper end secured to said fount, so that its lower end will be free,said flange surrounding said reduced portion of the fount, so that anannular space is formed between said reduced portion and said flange,and a drip cup 7 in the form of an annular trough having concentricouter and inner walls, the upper edges of which are free and the loweredge of which is attached to the bottom l0 of said cup, so that theupper end of said cup is open and its lower end closed, said inner andouter concentric walls of said drip cup having screwthreaded portions 8and 9 respectively, which are adapted to engage said screw-threadedflange 6 and said pipe or tube 4 respectively, said inner vertical wallof said drip cup being located in the annular space between it and thereduced portion of said oil fount, substantially as herein specified.

In testimony whereof I ax my signature in presence of two witnesses.
